1. The problem statement, all variables and given/known data A particle moving in a one-dimensional potential is in a state such that its wavefunction at time t=0 is: Psi(x,0)=A(x-a)x, 0<=x<=a, and Psi(x,0)=0, otherwise. Sketch |Psi(x,0)|^2, which gives the probability distribution describing the position of the particle at time t=0. 2. Relevant equations As above 3. The attempt at a solution I am thrown by Psi in this question. It doesn't even resemble a wavefunction. Am I simply supposed to square the absolute value of the polynomial?
